Multiple subnet and WINS server

I have a Linux box with two interfaces for the private LAN (eth0,
eth1) and another one connected to the Internet. I have two subnets in
my LAN (192.168.0.0/24 and 192.168.1.0/24) and eth0 and eth1 are the
gateways of either subnet (192.168.0.1, 192.168.1.1). I have a Samba
server running in the Linux box, and this Samba server is at the same
time the local master browser and a WINS server, there is only one
WINS server in the net.

I am having some problems when trying to do SMB browsing between the
two subnets, here I attach some of the relevant parts of my smb.conf
in the Linux box:

-----------------------------------------------------------------------------
hosts allow=127. 192.168.0. 192.168.1.
....
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
....
interfaces=192.168.0.1/24 192.168.1.1/24 127.0.0.1/8
bind interfaces only=yes
....
#To be the LMB
local master = yes
os level = 255
preferred master = yes
....
#To be the WINS server
name resolve order = wins lmhosts bcast
wins support = yes
dns proxy = no
-------------------------------------------------------------------------------

Since in the Linux box Samba is binded to both interfaces, .1.1 and
..0.1, should I specify as a WINS server for the clients of each
subnet the gateway, so 192.168.0.1 as a WINS server of 192.168.0.0/24
and 192.168.1.1 as a WINS server of 192.168.1.0/24 ? Or I could say in
both WINS server 192.168.0.1 for instance ? Or this simply doesn't
matter ?

The IP routing is working perfectly between the two subnets, so I
don't know why am I having problems, do u see any mistake in the
configuration or sth that maybe I could have missed ?

Thanks
